12 2) WJFE 300 MODULAR VIDEO UP

13 2) WJFE 300 MODULAR FIRE INSIDE AN INFRASTRUCTURE REPRESENTS A VERY DANGEROUS SITUATION FOR THE OPERATORS AND FOR THE SAME STRUCTURE. WJFE 300 MODULAR ALLOWS THE OPERATOR TO ACT IMMEDIATELY FROM OUTSIDE OF THE PLACE WHERE THE FIRE DEVELOPED 13

14 2) WJFE 300 MODULAR WJFE 300 MODULAR ALLOW THE FIRST FIRE ATTACK IN EFFECTIVE AND SAFETY MODE IN: CONFINED ENVIRONMENTS POTENTIALLY EXPLOSIVE AREAS ENVIRONMENTS REQUIRE THE MINIMUM USE OF WATER HIGH TEMPERATURE AREAS NEED TO BE COOLED TANKS (MOBILE AND FIXED) THAT CONTAIN EXPLOSIVE GASES 14

15 2) WJFE 300 MODULAR WJFE 300 MODULAR system 11,5 kg 3.6 kg empty 23,6 kg full 7,5 kg 560mm 31 kg 600mm 900mm 127,5 kg 15

16 2) WJFE 300 MODULAR Vacuum Abrasive cartridge quick connection Abrasive on/off trigger High pressure water trigger Adjustable shoulder stock Cutting nozzle High pressure water connection Abrasive cartridge Micronizer nozzle (water mist) Adjustable handle 16

17 2) WJFE 300 MODULAR TECHNICAL DATA: WATER PRESSURE: 350 BAR FLOW RATE: 22 LITERS/MINUTE WATER AND ABRASIVE SPEED: 940 KM/H METAL OXID (ABRASIVE): Ø 0,25 1,5 MM DIMENSIONS OF NEBULIZED WATER PARTICLES: Ø ΜICRONES 17

18 2) WJFE 300 MODULAR JET LENGTH: 8 10 METRES 18

19 2) WJFE 300 MODULAR JET LENGTH: 15 METRES 19

20 2) WJFE 300 MODULAR CONSIDERING 1 LITER OF WATER: A drop with the volume of of water, at a pressure of 1 bar, has a contact surface with the atmosphere of. of nebulised water, at a pressure of, generates, for a total contact surface with the atmosphere of 30 m2, which is than the one generated. 20

21 2) WJFE 300 MODULAR The firefighting nebulized water system, is based on following principle: REPRESENTATION OF THE FIRE DEVELOPMENT 1) COOLING: the nebulized water drops are very small and absorb a high quantity of heat. One liter of nebulized water at the pressure of 350 BAR has a 30 m² surface and absorbs 620 Kcal of energy that becomes vapour. This energy is substracted to the fire. The cooling effect reduces the pressure inside the room, this is an advantage for the watermist spread. OXYGEN (AIR) FUEL INNESCO IGNITION 2) OXYGEN DILUTION: the water becomes vapour, and expands its volumet up to times, diluting the present oxygen concentration. The quantity of oxygean near the fire is reduced from 21% to 6% ) SHIELD EFFECT: Fog and steam, mixed together inside the room, increase the cooling effects. This expansion will suppress the fire with 200g/m3 water in closed environments. 2 21

22 2) WJFE 300 MODULAR PROCEDURE: 1. First identify with a thermal imagers from where it will be better attack the fire 2. Drill the wall that separate from the fire, in the point indicated by the thermal imagers. 3. Nebulize the water in the closed compartment where the fire developed. 22

23 2) WJFE 300 MODULAR RESULTS: Gases fast cooling in the fire area Internal surfaces fast cooling Reduction of the oxygen concentration Thermal energy absorption BACKDRAFT STEPS ALLOWS THE OPERATORS TO ENTER WITHOUT BACKDRAFT RISKS. 23

24 2) WJFE 300 MODULAR 1. MAJOR SAFETY FOR OPERATORS 2. SPEED AND AGILITY OF USE 3. POSSIBILITY OF USED FROM A SINGLE OPERATOR 4. LOW WATER USE 5. IT CAN BE CARRIED ON SMALL VEHICLES OR SHIPS 6. DOESN T INTERFERE WITH ELECTROMAGNETIC FIELDS 7. POSSIBILITY TO CHANGE THE ABRASIVE CARTRIDGE WITHOUT TURNING OFF WJFE 300 MODULAR 8. USING THE EXTINGUISHING PRODUCT WITH WATER (WATER MIST) REDUCES THE INTERVENTION TIME. 24

25 2) WJFE 300 MODULAR 25

26 Test realized by Italian Navy with WJFE 300 MODULAR TRAINING CENTER OF ITALIAN NAVY WJFE 300 MODULAR 26

27 Test realized by Italian Navy with WJFE 300 MODULAR TEST EQUIPPED SPACE FOR THE TEST WITH THERMO-WAXES. DIMENSIONS: 8x8x4 M (256 M 3 ) FIRE CLASS OF TYPE: A (SOLID), B (LIQUID) (WOOD AND DIESEL) 27

28 Test realized by Italian Navy with WJFE 300 MODULAR INITIAL DRILLING WITH TEMPERATURE OF 700 C OUTSIDE INSIDE THE THE CHAMBER CHAMBER With smoke and vapour H. 0:00 400C H. 0:00 DRILLING TIME: 10 SECONDS 28

29 Test realized by Italian Navy with WJFE 300 MODULAR SITUATION AFTER SECONDS OUTSIDE THE CHAMBER Without smoke and without vapour INSIDE THE CHAMBER 50C After seconds, the internal temperature allows operator to enter. In this test was utilized only 50 l of water. 29
